A magnitude 6.8 earthquake struck close to the Solomon Islands in the South Pacific Ocean, just days after the archipelago was hit by another strong earthquake, the U.S. Geological Survey said on Friday.

The quake, initially reported as a magnitude 6.9, struck at 8:45 a.m. on Saturday (2145 GMT on Friday). Its epicenter was located 224 km east of Kira Kira at a depth of just 37 km below the seabed.

The Pacific Tsunami Warning Center said the quake had not triggered a tsunami.

The Solomon Islands and nearby South Pacific nations, which were struck by a magnitude 7 earthquake last week, are still recovering from a devastating cyclone that hit the region in March.
